I am a total rookie when it comes to drum brakes, so now I wonder: How do I know that they are fitted correctly? Look at those washers on top mount for the brake shoes (where the two springs are attached). Should they really be there? Are they needed to push the brake shoes in place against the plate?
If I want to buy spare parts (spring, shoes, dust covers for the two adjust holes in the back of the plate, etc), where do I find them?
